Undulations on Mars
Click for full image.
Time for a cool image that makes no sense. The photo on the right, cropped to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on November 15, 2019 of the floor of a crater, dubbed Dokka Crater, located in the high latitudes of the Martian northern lowlands. Uncaptioned but labeled “Undulations on Dokka Crater Ice Dome,” it shows a region of weird complex wave features, reminiscent of another weird Martian geological feature called brain terrain.
The problem is that brain terrain is generally found in the mid-latitudes, not the high latitudes. Both this feature and brain terrain however appear to associated with ice. In this case, these undulations are occurring on the ice dome that apparently sits inside Dokka crater, which is also likely to be related to the islands of ice found in many high latitude craters on Mars in the southern hemisphere..
In the case of the southern hemisphere ice-filled craters, scientists have found evidence suggesting that global wind patterns might affect their shape and placement within the craters. One wonders if this same factor is a part cause for these undulations in this northern hemisphere crater.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to
